Zamnesia Seeds - Jack Herer Automatic: An autoflowering triumph

Named after cannabis legalization pioneer and author of "The Emperor Wears No Clothes", Jack Herer is a multi award-winning strain that has gained legendary status. Originally created by Sensi Seeds, today, almost every seed bank carries their own take on this famous cannabis favourite.


The original Jack Herer is a balanced (50% sativa, 50% indica) hybrid that is only available as regular cannabis seeds. However, many slightly different versions of the strain can be found today that vary in some regards. What all of them have in common, however, is high potency.

Genetics 50% Sativa / 50% Indica
Parents Shiva Skunk #1, Northern Lights #5, Haze
THC 15%+
CBD Medium
Flavours Fruity, Skunky, Pine, Spicy
Effects Upbeat, Euphoric, Relaxing

Jack Herer bears the name of one of the most influential cannabis activists in Europe: Jack Herer. The cross between Shiva Skunk #1, Northern Lights, and Haze was originally created by Sensi as a perfectly balanced 50/50 indica/sativa hybrid. The many variants that followed would either lean slightly to the indica or sativa side, although sativa-dominant Jack cultivars are more common.

Depending on the phenotype, Jack Herer can measure from 15% to well beyond 20% THC, making it quite a potent variety. Since Jack Herer tends to produce a more cerebral effect than a physical one, it is best enjoyed as an inspiring daytime smoke.



Jack Herer isn’t particularly difficult to grow. Due to its robust hybrid nature, it is suitable for growers of most experience levels and churns out good yields in most environments.

Grow Difficulty Beginner / Intermediate
Best suitable to grow Indoor / Outdoor
Climate Dry, Warm, Sunny
Variety Feminized
Height Indoor 100 -180cm
Height Outdoor 180cm
Flowering Time 7 - 10 weeks
Harvest period (outdoor) Late-September/ Early October
Yield Indoor 500-600g/m²
Yield Outdoor 800–100g/plant

Jack Herer is a relatively easy strain to grow, with no special requirements. However, at times reaching 180cm or more in height, growers will want to ensure they have ample space.

Like many other sativa-leaning strains, Jack Herer has decent resistance to diseases, mould, and pests. This makes the strain very low-maintenance. Grown outdoors, Jack Herer does best in a dry, warm, and sunny climate. In good outdoor conditions, growers can expect to harvest 500g/plant (with some phenotypes offering considerably more) after 7–10 weeks of bloom. Harvest takes place in late September or early October.

Indoors, Jack Herer adapts well to various setups. Growers can see good results in both soil and hydroponics. In these setups, 500–600g/m² is possible in optimal conditions.

Jack Herer is a great resin producer. This makes it a good variety to enjoy in a vaporizer and for those who want to make concentrates and hash.



Jack Herer combines citrus and spice notes into a decadent and complex flavour profile. When smoked, intense lemon and orange notes join a base of sweetness, making for a very enjoyable smoke. One can also detect herbal or grassy flavour notes and the occasional Skunk or woody accent.

When it comes to Jack Herer’s powerful effect, up to 24% THC in the most potent varieties ensures a sativa high par excellence. The effect kicks in immediately and lasts for several hours. The high is mainly cerebral, with only a slight body buzz.

Due to its energising and upbeat effect, Jack Herer is a favourite among active and creative smokers who use it during their daily exploits. It is also a very social smoke that can facilitate deep, meaningful conversations, or can simply make for a silly and enjoyable time with friends. As you might guess, this heady effect is best enjoyed during the daytime.


Jack Herer has rightfully earned legendary status among cannabis enthusiasts. Its great taste and awesome effect make it one of the best sativa hybrids one can set a light to. Honour this strain’s namesake by growing your own Jack Herer!

    Netter Strain, aber keine Top Sorte
    Netter Strain, duftet Herrlich. Wirkung keine Ahnung, da noch nicht geraucht. Pflanzen bleiben relativ klein und geben durchschnittlich viel ab.
